Hi everyone,

I use Keycloak in my Vue SPA and I obtain my tokens using the Keycloak endpoints, with custom code instead of using keycloak-js adapter.

I now want to implement SSO. I know that I need to embed the `login-status-iframe.html`. I suppose that when my SPA loads, a check will be made inside iframe to see if the user is logged in or not; if user is authenticated, an authentication flow will be initiated.

However, I dont know how to use the iframe to see if user is authenticated in keycloak. Can anyone help? Thanks!
